Dataset of electricity and heat demand in a city district in Belgium. For the time period of the data, the district was still under construction and no full inhabitation of the buildings was present. Electricity data include electricity demand for: Individual households EV charging stations Decentralised waste water treatment Heat pump District heating pumps Vacuum network pumps Miscellaneous 'Total' in the electricity dataset (ElectricPower) refers to the sum of the separate time series. 'Total measured' is a measurement of the total electricity use (in W). Data isaveraged out over 15 minutes and expressed in kiloWatt before June 6, in Watt after that date.The electricity demand for the individual households (ElectricPowerPrivateUnits) is expressed in Watt for the complete period. The heat demand data (HeatDemand) describes the heat demand of the complete district, i.e. all private living units as well as common areas, office buildings, sports hall. Like electricity demand data, heat demand data isaveraged out over 15 minutes and expressed in kiloWatt before June 6, in Watt after that date.
